For context, Suisei's voice is extremely well trained, she's almost always in tone and her control is exceptional. On top of that she's had years of professional trainning and is consistently pushing her boundaries.

But then there's Risu.

Risu is an anomaly, a very rare outlier. She has the raw talent that only 1 in 100 million have. She has zero professional training and is entirely self taught. And yet the absolute raw ability of her voice is incomparable to anyone in hololive. For a fact, the moment she able to receive professional training and control the beast that is her voice she will be the best vocal talent in hololive by a country mile, hell she could even stand up to some of the best talent in the world once she has trained.

I don't know if Suisei knows how raw her voice is, but if she doesn't already know Risu isn't professionally trained at all, she'd probably fall to her knees.
